examples/std/type_c: Remove basic example

[RobertZ2011]

This example doesn't need to be a test because it tested basic message passing code which is covered by existing integration tests.

Pull request overview

This PR removes the type-c-basic std example binary, aligning the examples workspace with the intent that basic Type-C message passing is already exercised by existing integration tests.

Changes:

• Deleted examples/std/src/bin/type_c/basic.rs (the type-c-basic example).
• Removed the corresponding [[bin]] entry from examples/std/Cargo.toml.

File	Description

examples/std/Cargo.toml	Drops the type-c-basic bin target so the examples workspace no longer builds/exports it.
